The present application is a national stage filing under 35 U.S.C. §371 of PCT/EP2005/053728, filed on 29 Jul. 2005. The present application also claims priority under 35 U.S.C. §119 to Spain patent application Serial No. 200401966 filed on 30 Jul. 2004.

The present invention relates to new tyrosine derivatives acting as PPARγ modulators, as well as to processes and intermediates useful for their preparation, to pharmaceutical compositions containing them and their application in medicine.

BACKGROUND ART

Peroxisome proliferator activated receptors (PPARs) belong to the superfamily of transcription factors known as nuclear receptors. This family includes steroid, retinoid and thyroid hormone receptors. Three sub-types of PPARs have been identified in humans, rodents and Xenopus laevis. They are PPARα, PPARβ/δ and PPARγ, each encoded by a different gene and showing different tissue distribution.

The gene encoding for PPARγ is transcribed in humans in three different mRNA isoforms (PPARγ1, PPARγ2 and PPARγ3) through different splicing and promoter usage (Fajas et al., J. Biol. Chem. 1997, vol. 272, p. 18779-18789). The PPARγ1 isoform shows a wide tissular distribution, while PPARγ2 and PPARγ3 are confined to certain tissues: PPARγ2 is expressed only in adipose tissue and PPARγ3 in adipose tissue as well as in macrophages (Fajas et al., FEBS Lett. 1998, vol. 438, p. 55-60).

Differences detected in tissue distribution as well as in the activation profile of the PPARγ isoforms suggest they are involved in a variety of physiological functions playing a central role in glucose homeostasis and lipid metabolism (Vamecq et al., Lancet 1999, vol. 354, p, 141-148). These functions include, for example, lipidic transport in plasma and catabolism of fatty acids, regulation of insulin sensitivity and blood glucose levels, differentiation of macrophages that form atherosclerotic plaques, inflammatory response, carcinogenesis, hyperplasia, and adipocyte differentiation, the latter being the most verified function of the PPARγ (Grimaldi, Prog. Lipid Res. 2001, vol. 40, p. 269-281; Schiller et al., J. Biol. Chem. 2001, vol. 276, p. 14133-14137). Thus, the discovery of these transcription factors has provided new pharmacological targets for the development of useful therapeutic agents for the prevention and treatment of metabolic diseases such as diabetes, obesity and dyslipidaemia.

Non-insulin dependent diabetes mellitus (NIDDM) or type 2 diabetes is characterized by an insulin resistance in peripheral tissues, including muscle, liver, and adipose tissue. Glitazones, selective PPARγ agonist compounds, are drugs that reduce insulin resistance and lower blood glucose levels. Currently two products belonging to this family, rosiglitazone and pioglitazone, have been approved for the treatment of type 2 diabetes in humans.

A great effort has been made in recent years to design new drugs that improve the side effect profile of the first glitazones, show a greater affinity as a PPARγ ligands, and increase their potency in type 2 diabetes. This rational design has yielded structurally diverse compounds that show great potency and selectivity (e.g. farglitazar).

PPARγ agonists have had shortcomings which have so far detracted from their attractiveness, such as liver toxicity (especially troglitazone), weigh gain, edema, heart weight gain (in rodents) and adiposity, as well as modest efficacy in monotherapy for type 2 diabetes. These facts have provided an incentive to develop improved insulin sensitizers.

Compounds totally or partially blocking PPARγ activity have demonstrated to inhibit adipocyte differentiation. Thus, full antagonists constitute an effective treatment for obesity. Moreover, compounds that are partial agonists in addition of being antagonists may be particularly desirable because they are effective in treating not only obesity but also in controlling hyperglycemia. The PPARγ antagonists/partial agonists are therefore effective in treating obesity and other symptoms that generally occur in non-insulin dependent diabetes, such as elevated plasma levels of glucose, tryglicerides, and insulin.

Recently, there have been reports of compounds that are PPARγ antagonists or partial agonists (WO01/30343, WO02/08188, WO2004/020408), which are useful for the treatment of obesity and type 2 diabetes, with reduced side effects (Berger et al., Trends Pharmacol. Sci. 2005, vol. 26, p. 244-51).

Examples of partial agonists in clinical development for diabetes are (−)-halofenate (metaglidasen), FK 614 (Minoura et al., Eur. J. Pharmacol. 2004, vol. 494, p. 273-8), T131 (Li et al., 64th Annu. Meet Sci. Sess. Am. Diabetes Assoc. (June 4-June 8, Orlando) 2004, Abst 659-P), LY818 (Reifel-Miller et al., Diabetes 2003, 52 (Suppl. 1): Abst 614-P) and telmisartan, an angiotensin II blocker approved for the treatment of hypertension, with PPAR partial agonistic activity at concentrations achievable at plasmatic levels during treatment (Kurtz et al., Acta Diabetol. 2005; vol. 42 Suppl 1: S 9-16) which are currently in phase II of clinical development.

In Henkel et al., J. Med. Chem. 1998, vol. 41, p. 5020-5036; Collins et al., J. Med. Chem. 1998, vol. 41, p. 5037-5054; Cobb et al., J. Med. Chem. 1998, vol. 41, p. 5055-5069, WO 94/29285 and in WO 97/31907 de N-(2-benzoylphenyl)-L-tyrosine derivatives are described as being potent and selective PPARγ agonists. Documents WO 03/011814 and WO 03/011834 disclose N-(2-benzoylphenyl)-L-tyrosine derivatives as partial PPARγ agonists. Document U.S. Pat. No. 6,274,608 describes N-(2-benzoylphenyl)-L-tyrosine derivatives as being useful in the treatment and/or prevention of conditions mediated by Retinoid X Receptor (RXR) and the PPAR families.

Obviously, it is of great interest to provide new therapeutic agents that modulate PPARγ.

A compound of formula II may be obtained as shown in the above scheme by Williamson ether synthesis (see for instance Bal-Tembe et al., Bioorg. Med. Chem. 1997, 5, 1381-1388; Cantello et al., J. Med. Chem. 1994, vol. 37, p. 3977-3985 or EP 875510) or by Mitsunobu conditions (Mitsunobu, Synthesis 1981, 1; Hughes, Org. React. 1992, 42, 335).

In the first case, phenol ester III may be reacted with R2-LG (IVa), wherein LG represents a leaving group, such as for instance a halogen including —Cl, —Br, —I or an alkylsulfonate or arylsulfonate, including mesylate, tosylate or nosylate. This reaction is carried out in the presence of a base, such as NaH, K₂CO₃ or Cs₂CO₃, in a solvent such as N,N-dimethylformamide, acetone or ethyl acetate, at a temperature comprised between room temperature and the temperature of the boiling point of the solvent, preferably heating.

In the second case, a compound of formula III may be reacted with an alcohol of formula R2-OH (IVb) using for example, diethyl azodicarboxylate (DEAD) and triphenylphosphine in tetrahydrofuran as a solvent, at a temperature comprised between room temperature and the temperature of the boiling point of the solvent, preferably at room temperature.

Isolated enantiomeric forms of formula Ia and Ib can be obtained either by chiral resolution of a compound of formula I or starting from the corresponding chiral compounds IIIa and IIIb respectively.

A compound of formula II wherein R2 represents —(CH₂)_(s)—N(COR3)-A-J-T (i.e. compound of formula IIa) may also be obtained by acylation of a compound of formula Va with a compound of formula R3-COX (VIa), wherein X represents halogen, preferably Cl.

This reaction is carried out in the presence of a base such as triethylamine, in a solvent such as dichloromethane or ethyl acetate, at a temperature comprised between room temperature and the temperature of the boiling point of the solvent.

Some compounds of formula IIa can also be obtained by reacting a compound Va with the corresponding acid of formula VIb (see for instance Elmore, Amino Acids Pep. Proteins 2001, 32, 107-162). This reaction is carried out in the presence of a coupling agent, such as the combination of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide (EDC) and 1-hydroxybenzotriazol (HOBT) in the presence of a base such as triethylamine, in a solvent such as ethyl acetate or tetrahydrofuran, at a temperature comprised between room temperature and the temperature of the boiling point of the solvent.

Some compounds of formula II wherein R2 represents —(CH₂)_(s)—N(R4)-B-J-T (i.e. compounds of formula IIb) may also be obtained by reacting a compound of formula Vb with an alkylating agent of formula R4-LG (VII), wherein LG has the meaning previously described.

This reaction is carried out in the presence of a base, such as K₂CO₃, in a suitable solvent, such as N,N-dimethylformamide or acetonitrile, at a temperature and the temperature of the boiling point of the solvent, preferably room temperature.

Alternatively compounds of formula II can be obtained by solid synthesis using different types of polimeric solid resins, such as Wang or 2-chlorotrityl resins (Collins et al. J. Med. Chem. 1998, 41, 5037-5054). Compounds of formula III can be prepared following similar procedures to those described in Cobb et al., J. Med. Chem. 1998, 41, 5055-69.

Compounds IVa and IVb wherein R2 represents —(CH₂)_(s)—N(R4)-B-J-T (i.e. compounds of formula IVaa and IVba respectively) may be obtained as shown in the following scheme:

Compound VIII is acylated with a compound of formula IX to yield a compound of formula X, wherein R9 represents —CO₂(C₁-C₄)alkyl or —OCO(C₁-C₄)alkyl, under the same conditions as the reaction of compound Va with VIa to give compound. IIa. Reduction of compound X with a reducing agent such as lithium aluminium hydride in diethyl ether affords compound IVba.

Alternatively, compound VIII can be reacted with an alkylating agent of formula XI to afford compound IVba (Daoud et al., J. Indian Chem. Soc. 1989, 66, 316-318). Compound of formula IVaa is obtained by converting the hydroxyl group of compound IVba into a leaving group. This reaction may be carried out using a sulfonyl halide such as methanesulfonyl chloride in the presence of a base, such as pyridine or triethylamine in a solvent such as dichloromethane or chloroform. Alternatively, compound IVba can be reacted with a halogenating agent such as SOCl₂ in a a solvent such as tetrahydrofuran.

Compound VIII can be also converted directly into a compound of formula IVaa by reaction with a compound of formula XII, wherein each LG independently represents a leaving group as defined above, in the same conditions as described for the conversion of VIII into IVba.

A compound of formula V (including compounds of formula Va and Vb) may be obtained using two different synthetic sequences as shown in the following scheme:

Phenol III can be reacted with a protected amine of formula XIVa or XIVb, to yield a compound of formula XIII, wherein R8 represents -A-J-T or —B-J-T, LG represents a leaving group as previously described and PG represents a protecting group, such as for example, trifluoroacetyl or 2-nitrobenzenesulfonyl. The reaction is carried out under the same conditions described for the conversion of a compound of formula III into a compound of formula II. Compound V is subsequently obtained by deprotection of compound XIII. This reaction is carried out under different conditions depending upon the nature of the protecting group (see for instance Harland et al. Synthesis 1984, 941-43, Hirschmann et al. J. Amer. Chem. Soc. 1993, 12550-12568 for the group trifluororacetamide and Lin et al. Tetrahedron Letters 2000, 3309-3313 for the 2-nitrobenzenesulfonylamide group).

Alternatively a compound of formula V can be obtained by reacting phenol III with a secondary amine of formula XVa by Williamson ether synthesis. Compounds of formula VIII are commercially available or can be prepared by methods similar to those described for instance in WO 03/53966 or EP 875510. Compounds XIVa and XIVb can be obtained by reaction of the corresponding unprotected amine of formula XV and a protecting group (see Protective Groups in Organic Synthesis, John Wiley & Sons, 3rd Edition, 1999).

A compound of formula XV can be obtained using the following synthetic scheme:

Compound XVI is acylated to afford compound XVII under the same conditions for the reaction of compound Va and VIa to give compound IIa. Reduction of compound XVII gives compound XVb under the conditions described for the reduction of compound X. Compounds XVb wherein the amino group is less reactive than the hydroxyl group can be converted into compounds XVa under the conditions described for the conversion of IVba into IVaa.

Moreover, a compound of formula XVc can be obtained starting from a compound of formula XVIII.

This conversion can be carried out by reaction with an aldehyde of formula R10-CHO (XIX), wherein R10 represents R8 wherein the group attached to the N is —CH₂, in the presence of a reducing agent, such as triacetoxyborohydride or cyanoborohydride in a solvent such as 1,2-dichloroethane. Alternatively, compound XVIII can be reacted with compound XX or a derivative thereof to afford the corresponding amide as previously described. The reduction of the resulting product gives rise a compound of formula XVc. Compounds VIa, VIb, VII, IX, XI, XII, XVI, XVIII, XIX and XX are commercially available or can be easily obtained by conventional methods.

As it will be obvious to a person skilled in the art some of the reactions described above can also be carried out on compounds of formula I.

PPARγ2 Binding Assay

The cDNA encoding for the open reading frame of the hPPARγ2 was amplified by PCR (polymerase chain reaction) and inserted in the plasmid pGEX-4T-2. This construction (pGEX-hPPARγ) was introduced into E. coli where it was overexpressed and semipurified as a fusion protein with glutathione S-transferase (GST) (Elbrecht et al., J. Biol. Chem. 1999, 274, 7913-7922). The binding of the compounds to the GST-hPPARγ2 s was determined by modifications in the method described by Lehmann et al. (J. Biol. Chem. 1995, 270, 12953-12957). The receptors (2.5 μg) were incubated in 96-well plates in the presence or in the absence of the products with [³H]BRL-49853 (100 nM) for 3 h at 4° C., in a final volume of 200 μL of buffer Tris-HCl 10 mM pH:8.0, containing KCl 50 mM and DTT 10 mM. Non-specific binding was determined in the presence of BRL49853 100 μM. The reaction mixture was transferred to a Multiscreen Durapore (Millipore) microplate containing glutathione-Sepharose 4B in every well. The reaction mixture was left to incubate with the resin during 10 min, and then centrifuged at 735 g during 2 min. To dissociate the receptor bound to the resin, reduced glutathione 10 mM is added and incubated during 10 min. The receptor was eluted by centrifugation. Then, scintillation liquid was added to the elution and the contained radioactivity was quantified by liquid scintillation spectroscopy (Microbeta Wallac, Perkin Elmer).

LBD-hPPARs Transactivation Assay

COS-7 cells were cultivated in 24-well plates and transfected with the pFACMV plasmids that encode the chimeric proteins containing the GAL4 DNA binding domain fused to the PPARγ LBD. The reporter plasmid for the foregoing constructions was pFR-Luc, which contains five repetitions of the GAL4-response element in front of a promoter that controls the transcription of the luciferase gene. Lipofectamine was used as a transfection agent. The plasmids of the chimeric receptors and the reporter gene were inserted in the cells by transitory transfection in COS-7 cells in culture. When the products were added to the culture for 48 h, the luciferase activity showed the effect of the PPAR activity modulation on the transcription of the reporter construction (Wright et al., J. Biol. Chem. 2000, 275, 1873).

Cloning of Human PPARγ2

The human PPAR cDNA was amplified through RT-PCR. For hPPARγ2, RNA was obtained from human white adipose tissue. Each amplified fragment was cloned into pBluescript (Stratagene®) and sequenced. One clone for each construction was selected and used as template for further subcloning and PCR amplifications.

GST-Fused Protein Construction

To generate this chimeric protein, the complete cDNA of the human PPAR was cloned into pGEX4T2 (Amersham Biosciences). The fragment was obtained from the pBluescript-cDNAs clones digested with endonucleases. To assess the plasmid identity and to ensure the in-phase cloning of the proteins, pGEX construction was sequenced. GST-hPPARγ2 fusion protein was generated in Escherichia coli (BL21 strain DE3). Cells were cultured in LB medium to a density of A600=1.6 odu, and induced for overexpression by addition of isopropyl-1-thio-β-D-galactopyranoside (IPTG)-induced cultures to a final concentration of 0.5 mM. The IPTG-induced cultures were grown at room temperature o/n, before cells were harvested by centrifugation at 5000 g for 15 min. After sonication, the GST-fusion protein was purified from the cell pellet using glutathione-Sepharose beads, following the procedure recommended by the manufacturer (Amersham Pharmacia Biotech). Excess of gluthatione was removed o/n by dyalisis at 4° C. Receptor purity was visualized by SDS-PAGE and protein content was determined by Bradford method. Receptor aliquots were stored at −80° C. until use.

Compounds of formula IIa shown in Table 5 were obtained starting from a compound Va and a compound of formula VIa or VIb, following one of the procedures G-H described below.

PROCEDURE G: To a 0.2 M solution of compound Va (1 eq) in dichloromethane or EtOAc, triethylamine (3 eq) and a solution of an acyl chloride VIa (1.2 eq) were added. After stirring for 18 h, the crude was treated with 5% NaHCO₃. The organic layer was washed twice with 5% NaHCO₃ and once with brine. The organic layer was dried over anhydrous sodium sulfate and filtered. The solvent was distilled off under reduced pressure. The obtained residue was purified by column chromatography.

PROCEDURE H: To a 0.3 M suspension of compound Va (1 eq) in EtOAc containing HOBT (1.5 eq) and EDC (1.5 eq), triethylamine (3 eq) was added. Then, carboxylic acid VIb (1 eq) was added and stirred for 18 h. The reaction mixture was treated with water, the organic layer was separated and the aqueous layer was extracted once with EtOAc. The combined organic layers were washed once with 5% NaHCO₃ and once with brine, dried over anhydrous sodium sulfate, and filtered. The solvent was distilled off under reduced pressure, and the obtained residue was purified by column chromatography.

methyl ester Compounds I:

Compounds I described shown in Table 6 were obtained starting from the corresponding ester derivative of formula II following any of the procedures J or K described below.

PROCEDURE J: To a 0.02 M solution of compound II (1 eq) in a mixture of THF:methanol (3:1) or THF, a 1 M aqueous solution of lithium hydroxide (1.5 eq) was added. The resulting mixture was stirred at room temperature for 18 h, then treated with HCl 1 N until pH=56, and extracted twice with EtOAc. The organic layers were dried over anhydrous sodium sulfate and filtered. The solvent was distilled off under reduced pressure.

PROCEDURE K: To a solution 0.03 M of compound II (1 eq) in methanol, potassium hydroxide (10 eq) was added. The resulting solution was stirred at room temperature for 18 h, then treated with HCl 1 N until acid pH=4-5. To the resulting suspension, water and EtOAc were added. The organic layer was separated and the aqueous layer was extracted once with EtOAc. The combined organic layers were dried over anhydrous sodium sulfate and filtered. The solvent was distilled off under reduced pressure.
